1387–1422, king of England (1413–22); son of Henry IV. He defeated the French at the Battle of Agincourt (1415), conquered Normandy (1419), and was recognized as heir to the French throne (1420)

1421–71, last Lancastrian king of England (1422–61; 1470–71); son of Henry V. His weak rule was blamed for the loss by 1453 of all his possessions in France except Calais; from 1454 he suffered periods of insanity which contributed to the outbreak of the Wars of the Roses (1455–85). He was deposed by Edward IV (1461) but was briefly restored to the throne (1470)

1457–1509, first Tudor king of England (1485–1509). He came to the throne (1485) after defeating Richard III at the Battle of Bosworth Field, ending the Wars of the Roses. Royal power and the prosperity of the country greatly increased during his reign
1491–1547, king of England (1509–47); second son of Henry VII. The declaration that his marriage to Catherine of Aragon was invalid and his marriage to Anne Boleyn (1533) precipitated the Act of Supremacy, making Henry supreme head of the Church in England. Anne Boleyn was executed (1536) and Henry subsequently married Jane Seymour, Anne of Cleves, Catherine Howard, and Catherine Parr. His reign is also noted for the fame of his succession of advisers, Cardinal Wolsey, Sir Thomas More, and Thomas Cromwell
1050–1106, Holy Roman Emperor (1084–1105) and king of Germany (1056–1105). He was excommunicated by Pope Gregory VII, whom he deposed (1084)

known as Henry of Navarre. 1553–1610, first Bourbon king of France (1589–1610). He obtained toleration for the Huguenots with the Edict of Nantes (1598) and restored prosperity to France following the religious wars (1562–98)
masc. proper name, from French Henri, from Late Latin Henricus, from German Heinrich, from Old High German Heimerich, literally "the ruler of the house," from heim "home" + rihhi "ruler." One of the most popular Norman names after the Conquest.
A SI derived unit of electrical inductance, especially of transformers and inductance coils. A current changing at the rate of one ampere per second in a circuit with an inductance of one henry induces an electromotive force of one volt.
American physicist who studied electromagnetic phenomena. He discovered electrical induction independently of Michael Faraday, and constructed a small electromagnetic motor in 1829. He also developed a system of weather forecasting based on meteorological observations. The henry unit of inductance is named for him.
A king of England in the early sixteenth century. With the support of his Parliament, Henry established himself as head of the ChristianChurch in England, in place of the pope, after the pope refused to allow his marriage to Catherine of Aragon to be dissolved. Since that time, except for a few years of rule under Henry's daughter Mary I, who was a Roman Catholic, England has been officially a Protestant nation.
In his personal life, Henry was known for his corpulence and for his six wives. He divorced the first, Catherine of Aragon. He beheaded the second, Anne Boleyn, for allegedly being unfaithful to him. His third wife, Jane Seymour, died soon after giving birth to a son. He divorced his fourth wife, Anne of Cleves, and beheaded his fifth wife, Catherine Howard, also for alleged infidelity. His sixth wife, Catherine Parr, survived him. He also had his close friend and adviser Thomas More executed because More would not support Henry's declaration that he was head of the church in England. Henry was the father of King Edward VI and of Queen Elizabeth I, as well as Mary I.
